    Great Mexican food with lots of options. Their sauces are delicious and salsas are spicy and flavorful. Might just be the best I’ve had in Boulder

    Great Mexican food. My family and I have been coming here for years. Margs are great, I usually get the Coin and my dad gets the gold rush. My go to order is the costilla ribs or the Efrain burrito. Have to get something with green chili, it has the right amount of heat

    Visited this establishment on a recent trip to Boulder and boy, were we pleasantly surprised! Some of the best authentic Mexican food I’ve ever had. After reading the Google reviews, we knew we were in for a good experience, but one never knows till they try it for themselves. Food was out of this world! Margaritas are also outstanding. During our entire trip to Colorado, this was by far our most enjoyable and best value meal. I highly recommend you give them a try if you are visiting Boulder or if you live in the area and have never been, I promise you won’t be disappointed!

    Winner! Best Mexican Food


    Efrain's II - 1630 N. 63rd St., Boulder, 303-440-4045 

    Our favorite dish at Efrain’s is a little something called blue corn enchiladas with chicken and a side of green chile to pour over the top, to give it a spicy kick. Oh, and a margarita or a Negra Modelo with lime. Sorry, just drooled a little bit on the keyboard. Efrain’s has been a Boulder County institution for more than two decades, delivering authentic northern Mexican cuisine from the state of Chihuahua. It is a recipe for a satisfying south-of-the-border experience. Olé.

    Efrain's Margaritas

    Ever tried the Mexican Ribs at Efrain’s? Sweet mother of Zeus, they are spicy. We’re not talking about your classic barbecue ribs, these babies are soaked for, like, days in green chile. And this may well be the best, hottest green chile this side of Taos. Makes the margaritas go down a lot quicker, let’s put it that way. The nice thing about this East County restaurant is that there are three locations, so no matter what ‘L’ town you live in, you’ll never be far from delicious Mexican food. But when ordering, keep an eye on the handy spicelevel scale that appears next to each dish on the menu. Your tongue will thank you later.

    2011 Best Mexican Food

    Ask Efrain what style he specializes in and he says laughingly, “REAL traditional Mexican food! Everything is fresh. We start cooking in the kitchen at 6 a.m., every day. I learned cooking from my mom; she is the best cook in the world, I think.” The original Efrain’s in Lafayette opened over two decades ago. Efrain had worked in other relatives restaurants, and pretty soon he decided that he wanted to start his own. Since then, Efrain’s has developed a loyal fan base who keep coming back for the chimichangas, fajitas and the chili verde. Efrain opened a second location in Boulder twelve years ago, followed by the Longmont Efrain's in 2005. Efrain's has won Boulder County's coveted People's Choice Award for the best Mexican food every year since the awards began in 2009. Thank you Colorado!!!!

    The combo plate was the perfect option to first-timers like myself to sample a few different items. And it was so huge, I took about half of it home for lunch the next day. Efrain’s is hands down one of the best deals in town, absolutely the best Mexican I’ve had in the area, and is so off the beaten path it is a great change of scenery. The only draw back to this is it is about a ten minute drive, which is unfortunate if you’d like to sample a margarita, or two. Nevertheless, it is absolutely, 100% worth the drive and possible wait, for hands-down the best Mexican food in town :)

    No question! And it's a family owned authentic restaurant, not a posuer place like some around town. Go for the beef enchilada or The Efrain. Green chile is not to be missed.

  • Some of Colorado's Best Green Chile

    Efrain's has a large menu of traditional mexican and southwestern dishes. But if you're looking for authentic green chile, this is the place to get it on the front range. None of this anemic, gelatinous goo the other places dribble over their fare. This is the real deal, with chunks of lean pork in a flavorful, roasted green chile sauce packing plenty of heat. Put out the fire with fresh made tortillas and perfectly mixed margueritas.
